My drum cover videos keep getting blocked or muted by greedy fatcats who think I'm stealing from them by posting videos of me drumming to their artist's songs so that I can get some constructive critisizm. There are countless other drum covers of the same song on Youtube, so why block mine? It makes no sence. Any help?

They've got the law on their side. Why they don't remove the other ones, I can't tell you, but if the people who own the copyright for the song don't want you to put it up there, you can't do anything about it.

Maybe it's because yours are actually good. Take it as a compliment. :)
